Recommended numbers for my pool

I read through pool school and was wondering if those numbers would be sufficient for my pool.

I'm targeting......

FC 3
PH 7.6
TA 90
CH 300
CYA 70
Borates 50

Those numbers give me a CSI of -0.26

Pool specifics are in my signature and also run a water fall when pump is running. I'm noticing a significant PH rise though with the fall on when the pump runs so I may turn the fall off more often to help stabilize the PH.

Re: Recommended numbers for my pool

No, you need a lower TA to reduce the rate of pH rising.

You said CSI was -.26, which made me nervous about suggesting you reduce TA any further. But I double-checked your numbers in the Pool Calculator; to make everything work out it looks like your water temp must be about 60F. CSI will go up as the temp goes up, so lowering your TA is probably okay.

Re: Recommended numbers for my pool

You actually want the CSI to be a little negative, -0.3 or a little lower in many case. The CSI inside the SWG cell is much higher than it is in the pool in general, and the same is true inside the heater (if you have one).
